Note: 1. C1/C2: filtering electrolytic capacitor (which is required), recommended the same brand, the same model, the same batch of electrolytic capacitors; 2. R1/R2: max operation voltage of R1/R2 should be above 450V. While using chip resistors, it is recommended to use several chip resistors in series to meet operation voltage; 3. R3(which is required): winding resistance; 4. C3 and C4 are output filer capacitors (which is required), they are recommended to be high frequency and low impedance electrolytic capacitors. Capacitance and rated ripple current of capacitors refer to the datasheets provided by the manufactures. Voltage derating of capacitors should be 80% or above. C5 is a ceramic capacitor, which is used to filter high frequency noise. C3, C4 and L1 form a pi-type filter circuit. Current of L1 and L2 refer to the datasheets provided by the manufactures, current derating should be 80% or above. TVS is a recommended component to protect post-circuits (If converter fails); 5. When working at full load at ambient temperature of -40 ℃ to -20 ℃ , following circuit parameters values are recommended: C1/C2(necessary): 33μF/450V; R1/R2(necessary): 1 MΩ; R3(necessary): 12Ω/2W; NTC(necessary): 10D-10.
